This invention relates to'improveinents in wing brace arrangements for railroad Spreaders and it consists inthe matters hereinafter described and more particularly pointed out in the 'appended'claims.

The primary object of the invention s to provide a novel improved wing brace a rrangement for railroad spreaders wherem 1n the braces are arranged in front and rear pairs of top and bottom braces thus bracing the top portion of the wing as well as the bottom against the load imposed upon thewing as when spreading materialwhereby the wing is held against a twistingaction tending to distort the same and its hinge plate.

lAfurther object of the invention is to provide anovel connection betv'veen the wing braceshaftsononesideof the spreader, whereby said shafts are caused to rock or turn in unison so that the associated braces act together.

These objects of the invention, as well as others, together with the many advanages thereof will more fully appear as I proceed with'my specification.

V In the drawings v v -Fig. 1 is a top plan view of a railroad spreader embodying my novel improved wing brace arrangement. 7 e j I Fig. 2 is a detail'vertical'sectional viewon anenlarged scale as taken'on the line 2-2 of Fig. 1. v

Fig. 3 is altransverse vertical sectional view through the spreader also on an enlarged scaleas taken on the line 33 of Fig. 1. 1

Referring now'in deailto thatembodi ment of the inventionillustrated in the accompanying drawings, lindicates as a whole thecar bodyof a railroad spreader and 2-2 indicatesthemain orsidespreader wings, with one of such wings located at each side of the car body. Each wing is pivoted at its front end to an associatedupright wing post 3 on,

the car body, by means of a vertical axis pin 4 carried by a hinge block 5 adapted for vertical movement in the post. At each side of the car body is arranged'a pair of top and bottom, longitudinally extending rock shafts 6.

and 7 respectively. The ends of said shafts are journalled in suitable brackets 8'and respectively, suitably supported from the underzframing of the car body, Oneof said shafts, is operatively connected to 'anfasso-z' ciatedupright power. cylinder 10 .on the car body by which said shaft maybe/rock'ed: or turnedin either direction as desired. Nearthe 'frontrend' of each shaft is fixed an"ai m lland- 12 respectively and the outer. ends ofrboth" arms are connected together; by a link 13' which has a bendal l therein near the top end; As is-apparent when power-is applied to' ofne of.=sa-id'-shaftsi-(preferably the bottom one) from the cylinder .10, both shafts-rock in unison v 'Associatedgwith each wing 2 is a front pair of top andbottom folding'braces 15 and 15 respectively, and a single rear brace bar 16. As all the folding braces are alike iniconstruc tion with'the' exception that-the rearb'raceis the longer, ,adescrip'tionof one will sufficefor all. ,Each folding brace: comprises innerffand outer brace arms I17 and 18 respectively, the adjacentf-jends of;- which sa're connected to gether by afknuckle joint 19;:which" permits said bars to be ffoldedltogetherin the manner ofia folding rule'ikEach arm mayorima'y not b'ettelescopic'in length, whichever manner. is desired.

When in operation, the materialwbeing spread piles up in front of the Wingand of 7 course imposes a heavy resistanceand strain thereto."
